Problem in Active Real-Time Database Application Active database and real-time databases have increased in recent times. Real-time database system is now an important part of technologies to support real-time processing (RTC), applications such as automatic tracking and object positioning application. Computer integrated manufacturing (CIM) process for air traffic control. Media server for real-time streaming-commerce-business and credit card transactions. In real-time database application data changes very rapidly and is dynamic. On the other hand, real-time database application has great potential. This paper will address the problems associated with real-time database activity, and we will discuss several alternatives for solving these problems. Real-time database is a very new area where little research has been done. On the other hand, the active real-time application has good potential. In this article we will focus on issues and issues such as semantics, assigning time constraints, and rule selection. Which we need to consider when designing or implementing a real-time database. And I will highlight the problems associated with event detection, rule triggering, rule selection, and evaluation in a real-time active database system.

Nowadays real-time database applications become so complex and require access to more data. Therefore… half the paper… the control mechanism would be eliminated. The high priority transaction is issued when it is running. The low priority transaction is already running and you can confirm its timeliness. Serialization consistency is the main requirement of the concurrency transaction. The result of read and write operations will be the same while the transaction is executed in serial order. There is no requirement on the actual order, as long as it guarantees some references to the order. [3] A model for data and transactions Processing transactions in a real-time active database system for e-commerce may require different data models and, for security reasons, most real data processing algorithms Temporal database scheduling in real-time application uses algorithms to reduce the workload and model the operating environment. Where this pattern is used in e-commerce database application where it requires security requirements.
